DANIEL F. KUSTER AND GUSTAV J'. NIEMAN-N, OF WASHTUCNA, WASHINGTON.

T all whom it may concern:

Be it known that we, DANIEL F. KUs'rER and Gusrav J. NIEMANX, citizensof the United States, residing at Vashtucna, in the county of Adams andState of ashing ton, have invented an Improvement in Plowing-Machines,of which the following is a specification.

Our invention relates to improvements in machines for plowing in which agang of concave-convex disks and plane disks are disposed on oppositesides of the central draft line, and has for its object to produce adevice which may be used for disking and throwing the dirt either to theright or left, thus making it possible to go along the side hill, andwhen the end of the strip is reached the machine may be reversed andretraced along the same side throwing the dirt down hill.

With these and other objects in view our invention consists in certainnovel features of construction, arrangement and combination of parts aswill be hereinafter fully described and pointed out in the claims,reference being had to the accompanying drawings, in which Figure 1 is aside elevation of our im proved plowing machine. Fig. 2 is a top planview of same. Fig. 3 is a rear elevation of the machine. Fig. 4 is aperspective view of the slide for adjusting the angularity of theconcavo-convex disk-carrying frame.

In carrying out our invention we use a cross-frame 1 from which aresuspended the plane disks 2 by hangers 3, the disks being separated byspools 4;; these plane disks being disposed at one side of the centralline of draft (in F 2 they are shown at the right). Near the left end ofthe crossframe 1 is pivoted a bar 5, said bar lying beneath the frame 1and having suspended from it the concavo-convex disks 6 by the hangers 7suitable spools 8 separating and spacing said disks. To the upper faceof bar is bolted a metal bar 9 which is offset at 10 to clear the end offrame 1 and is pivotally secured to the frame 1 by the same pivot 11which secures the bar 5 to the lower face of frame 1. The bar 9 is thenbent upwardly as at 12 and then horizontally as at 13 and has anelongated slot 14 near its end through which passes a threaded stud 15projecting from an angular slide 16, said slide being shaped to embracethe rear end Specification of Letters Patent.

PLOWING-MACHINE.

Patented Nov. 9, 1909. Serial No. 444,320;

of beam 17 which is secured to the upper circle member 18 of a turntableor fifthwheel, the lower circle member 19 being held to the upper by thebent clips 20 which are secured to the upper circle member 18. The lowercircle member 19 is rigidly secured to the cross beam 1.

The slide 16 for adjusting the angle at which the concavo-convex disksare set is made at its rear end in the form of a channel-iron 21 whichembraces the beam 17 and has a projecting ledge 22 on which the threadedstud 15 is mounted; the main por tion of the slide is open at the top asshown in F 1, the side members 23 extending forwardly alongside thebeam, and being pivotally connected at the forward ends to the bentstrap bars 24, whose forward ends are pivotally secured to the adjustinglever 25 which is bifurcated at its lower end and pivotally secured tothe beam at 26; the lever 25 is curved rearwardly so that the handle isin convenient reach of the operator on seat 27 mounted on a springsupport 28 secured to the beam 17 The lever 25 is provided with theusual spring actuated bolt 29 which engages a notched quadrant 30secured to the beam 17 it will thus be seen that the slide 16 has adouble pivotal connection with the hand lever 25 so that its mainportion will slide perfectly horizontal on the beam; as before statedthe rear end of the slide is pivotally connected to the end of the bar13 which is secured to the bar 5 carrying the concaveconvex disks 6, andby means of this pivotal connection working in the elongated slot let.the angle at which said concavo-convex disks may be set can be regulatedthrough the hand lever 25.

The beam 17 is pivotally secured near its rear end to the frame 1 by aking bolt 36 and side braces 37 extending from the said beam are rigidlysecured at their outer ends to the upper circle iron 18; these sidebraces are usually formed in a single piece being mortised into theunder face of beam 17 and having spaces 38 cut out on each side of thebeam to permit the side bars 23 of the slide 16 to move freely.Pivotally secured to the side braces 37 are the curved pawls 39, theupper ends of which extend past each other and rest on the spring footpiece which holds normally the said upper ends up and the lower outerends into notches 40 in the upper and lower circle irons of theturntable, the notches in each circle iron registering when the deviceis in lockedposition. 42 represents a retaining band which is secured tothe upper face of the side braces 37 and prevents the slide 16 frommoving vertically.

At a suitable distance in advance of the notched quadrant 30 a crossbeam 31 is rigidly secured in the outer ends of which are mounted thestandards 32 which are bifurcated and bent rearwardly at their lowerends 33, and carry the sustaining wheels or casters 34. In front of thecross beam 31 the beam continues as a tongue or pole to which the teamis hitched, the wheels 34 supporting the tongue.

Machines of this character are usually what are termed right-lapmachines, which disk and throw the dirt slightly to the right at thesame time; with this type of machine the difiiculty lies in the factthat the dirt is always thrown to the right and hence when used on aside hill, where one cannot go around the hill, it can be used only ingoing in one direction, or else the dirt has to be thrown up hill halfthe way, which makes heavy pulling and produces unsatisfactory results.

With our machine it is possible to go along the side hill and when theend is reached, the driver by pressing his foot on the spring foot piece35, the pawls 39 are lifted out of notches 4L0, releasing the turntableor fifth-wheel and the horses are swung in a half circle to the rightwhich by virtue of the attachment of the concavo-convex' disk sectionthrows the disks the opposite way to which they were set; the foot piece35 then being left free locks the turntable in this position and themachine can then be retraced alongside the last strip of ground, stillthrowing the dirt down hill. It will thus be seen that the draft on theteam is reduced to a minimum and side pull prevented, and that themachine is a reversible lap machine.

The brace irons 18 are secured at one end to the circle iron 18 andcrossing each other under pole 17 are secured at their forward ends tothe cross beam 31 as shown in Fig. 2.

The spring foot piece 35 which by upward pressure throws the pawls 39into locking position is provided with the bent extension 35 whichprojects forwardly over the pawls 39 and is bifurcated as at 35 so thatthe foot of the operator may not slip to either side.

The hangers 3 will be placed between every two disks.

1. In a plowing machine, the combination with a cross frame, a turntable carried by said frame, a beam mounted on said turn table, a planedisk section suspended from said frame at one side of its center, adished disk section pivotally suspended from the frame at the other sideof the center, and pivotal connections between the said dished disksection and the beam.

2. In a plowing machine, the combination with a cross frame carrying atone side of its center a plane disk section and at the other side adished disk section, said dished disk section pivotally suspended fromthe cross frame, a beam pivotally mounted on said cross frame, an armextending from said pivoted section over the beam, a slide mounted onsaid beam, a sliding connection between the arm of the pivoted disksection and the slide, and means for moving said slide to control theangle of the dished disks.

3. In a plowing machine, the combination with a cross frame carrying atone side of its center a rigid section of plane disks, and at the otherside of'its center, a section of dished disks and pivotally suspendedtherefrom, a turn table mounted on said frame consisting of upper andlower circle irons, a beam mounted on the upper circle iron, pawlscarried by said beam to lock the upper and lower circle irons, means forthrowing said pawls into locking engagement wit-h said circle irons, andmeans for unlocking the same, and pivotal connections between the disheddisk section and the beam.

In a plowing machine the combination with a cross-frame carrying atone side of its center a rigid plane disk section and at the other sideof the center a dished disk section pivotally secured to said frame, aslotted arm projecting from said section, a beam mounted on said crossframe, a slide mounted on the beam, a pin or stud projecting from saidslide and slidably engaging the slotted arm, a hand lever pivoted to thebeam, and connecting bars pivotall'y connected to said lever and to theforward end of the slide.
